New combo therapy aims to tackle Ultra-Resistant schizophrenia
NCT ID NCT05240976
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding an anti-inflammatory drug to an NMDA-enhancing agent can improve thinking and memory in people with ultra-resistant schizophrenia. About 80 adults who have not responded well to clozapine will receive the combination or a placebo. The goal is to see if this approach can better control symptoms and boost cognitive function.
